QNX 6.20 SOS for boot

I have add this line in /etc/rc.d/rc.local :
/opt/mysql/bin/safe_mysqld --user=mysql &
When I reboot (qnx under windows partition) :
Starting extra run commands
Starting mysql daemon with databases from /opt/mysql/var
I have hang up
Under Windows i make a boot floppy, It is the same failure
Thank you for your help

During boot I press space bar for input boot options
I press F1 , no result ??

there must be something wrong with your rc.local which hangs the boot process. See my post in this thread on how to recover from a “bad” rc.local:

btw, on how to autostart mysql, download the “mysql.server” from qnxzone.com/~fliu/ and make it executable. you will need to change it for the correct mysql pid, then try command line “mysql.server start” and “mysql.server stop” to start and stop mysql. Once you are happy with it, you can add it in your /etc/rc.d/rc.local (make sure rc.local is executable).

During boot I press space bar and F8
I launch “ph”
I can correct rc.local.
Now all work fine.
Thank you very much.
